Analysis layers

Six layers. One verdict.

Every scan runs the target through independent analysis layers. Each layer reports its own findings; the AI engine weighs them into the final grade.

DNS Records & mail authentication

A, MX, NS and TXT records, plus SPF, DKIM and DMARC. Missing mail authentication is the most common gateway for spoofing.

TLS Certificates & encryption

Certificate validity, issuer reputation, expiry window, protocol versions and HSTS. Weak TLS is treated as a hard penalty.

INTEL Blacklists & threat feeds

Presence on spam, malware and phishing blocklists. A single confirmed listing caps the grade at D.

WHOIS Registration & age

Registration date, registrar reputation and ownership transparency. Very young domains carry structurally higher risk.

INFRA Hosting & network

ASN reputation, shared-hosting density and geographic anomalies between claimed identity and actual infrastructure.

AI Lexical & look-alike detection

A language model scores the name itself: typosquats, homoglyphs, brand impersonation and phishing-style keyword patterns.

How it works

From domain to grade in three steps

  1. 01

    Submit a domain

    Paste any domain — from an email, an invoice, an ad, or a link you're not sure about. No account needed.

  2. 02

    Layers run in parallel

    DNS, TLS, threat-intel, WHOIS, infrastructure and lexical AI checks execute simultaneously and report raw findings.

  3. 03

    AI weighs the verdict

    The engine resolves conflicting signals into a 0–100 score and an A–F grade, with every contributing factor listed.

Reading the score

The A–F trust scale

Grades C and below always include the specific findings that lowered the score, so you can judge the context — a missing DMARC record is not the same as a live phishing listing.

FAQ

Questions, answered

What does the trust score mean?

It is a 0–100 rating condensed into an A–F grade, combining DNS health, SSL/TLS configuration, blacklist presence, domain age, WHOIS transparency and AI-detected phishing patterns. A and B are generally safe; D and F signal elevated risk.

Which signals does the AI analyze?

More than 40 signals across six layers: DNS and mail authentication (SPF, DKIM, DMARC), SSL/TLS certificates, threat-intelligence blacklists, WHOIS registration data, hosting infrastructure, and lexical AI analysis that detects look-alike and phishing-style names.

Is the scan free?

Yes. Single-domain scans are free with no account. Bulk scanning and continuous monitoring are available through the API for teams.

Can I check a link from a suspicious email?

Yes — that's the primary use case. Paste the domain from the link into the scanner and review the grade and individual findings before visiting the site or entering credentials.

Trust is measurable.
